Thx's Rob,... and the others who responded.

It gave me some good ideas to persue and I think I have what I was trying to accomplish now. Just need to do some fine tuning :)

Appreciate the help as always.

is it possible, with perl, to find the closest numerical value to a set value.
IE. a set value of 15 and I have five values, 208,258,56,123

is there a function too go through the five values array to find the closest to
15 ??


Hi Mike.

There's no built-in function, but it's simple to write one; the code below will
do what you want. It's not particularly efficient, but is more than likely
to be fast enough for you unless your list of values is huge.

HTH,

Rob


use strict; use warnings;

my $set = 15;
my @vals = (208, 258, 56, 123);

print closest($set, @vals), "\n";

sub closest {
  my $val = shift;
  my @list = sort { abs($a - $val) <=> abs($b - $val) } @_;
  $list[0];
}

**OUTPUT

56
